Well, maybe the title is little bit complicated. I'll try to explain what I need here. I have an ArrayList<PlayerParameters> which stores PlayerParameters class objects and my ExpandableListView displays some String values from this class (name, age, city etc.) I want to filter my items by the values. I've found a tutorial teaching how to create the search panel: https://medium.com/@makkenasrinivasarao1/expandablelistview-with-checkbox-radiobutton-in-android-af9ec9d81ddf. The question is how to connect this panel to my ArrayList and ExpandableListView.
This is a piece of code where I put my data to the ExpandableListView.
public void onCallback(ArrayList<PlayerParameters> playersList, ArrayList<String> playersNames) {
listDataHeader = playersNames;
String[] listDataHeaderArray = new String[listDataHeader.size()];
playersNames.toArray(listDataHeaderArray);
Collections.sort(listDataHeader);
listDataChild = new HashMap<String, List<String>>();
HashMap<String, ArrayList<String>> playerInfo = new HashMap<String, ArrayList<String>>();
for (PlayerParameters j : playersList) {
ArrayList<String> infoList = new ArrayList<String>();
infoList.add("Nickname: " + j.getNickname());
infoList.add("Age: " + j.getAge());
infoList.add("City: " + j.getCity());
playerInfo.put(j.getName(), infoList);
}
for (int i = 0; i < listDataHeader.size(); i++){
listDataChild.put(listDataHeader.get(i), playerInfo.get(listDataHeader.get(i)));
}
ExpandableListView expListView = view.findViewById(R.id.lvExp);
listAdapter = new ExpandableListAdapter(getActivity(), listDataHeader, listDataChild);
expListView.setAdapter(listAdapter);
expListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
@Override
public boolean onGroupClick(ExpandableListView parent, View v,
int groupPosition, long id) {
return false;
}
});
}
